Antirattler for window sashes



Patented July 7, 1931 UNITED A AT N FiCE'ji ALFRED THOMPSON GRANGER, or mnvovnn, NEW HAMPSHIRE ANTIRATTLER ron wmnow sAsHris Application filed April 15,.

This invention relates to anti-rattler or silencing devices for window constructions and the primary object of this invention is to provide an improved anti-rattler or silencing means carried by a sliding window sash or the like and engagingthe window stop for exerting a continual pressure against the window stop thereby eliminating all looseness and rattle when the windowsash is in an a opened or closed position.

trating a window framecontaining two sliding sashes equlpped with my improved device, he same being provided with the conventional window stop, the latter being shown broken away,

Figure 2 is a fragmentary detail sectional view taken substantially on the line 2-2 of Figure 1,

Figure 3 1s a fragmentary detail view showing 'mIy improved device partly in section and partly in elevation,

Figure 1 is an isometric view of thedevice per se,

Figure 5 is a diagrammatic view illustrating the blank from which the device is/made.

Referr ng more in detail to the'drawings, it will be seen that the reference character.

F designates a conventional type of window frame, the side members S of which are provided with the usual window', stops '5. The reference character W designates generally one of the sliding sashes mounted in the usual manner in the window frame.

The sash referred to is preferably the lower sliding sash of the window. In carrying out my invention two of the devices embodying the features of my invention are mounted on the top rail 6 of the window sash at each end formation and so formedas to-provide'an window frame whether the sash be in a'raisedj 1930. iSe ria1 No.444, 5j11.

of the rail for'cooperation with the adjacent window stop 5: p 1 p I Each of these devicesis formed from a single blank of metal of substantially L-shape apertured attaching flange 6 having an arm 7 extending laterally therefrom adjacent one i V end thereof. The arm 7 is suitably rolled inwardly toward the flange 6 to provide a cylindrical socket or housing 8. On one edge 0. thereof adjacent the flange 6 the arm 7 has formed integrally therewith a disk like extension 9 adapted to bend upwardly at substantially right angles to the arm 7 to provide an end wall for the housing or socket 8. i On its opposite longitudinal edge,.the arm 7 has a plurality of spaced spring fingers 11 projecting therefrom and, adapted to be a'r-,. ranged in an annular series when the arm is rolled upon itself for formingthesocket orhousing 8. These fingers 11 are bent inwardly toengage a relatively large ballbearing 1 12 normally urged outwardly at the open end of the housing 8 through the medium of a coil spring 13 arranged in said housing, one end of the coil spring bearing against the end wall 9, and the other'end bearing against the ball 12 as clearly suggested in Figure 3. I

In actual practice, the flange 6 is bolted, screwed'or otherwise secured to the top rail of the window sash by any suitable fastening means 14, inwardly from the end of the sash rail so as to position the socket or housing '8 directly opposite the adjacent window stop 5 whereby the spring pressed ball 12 will be 5 urged against the window stop 5.

The ball 12 being so pressed against the window stop will tend to hold the sash firmly in place obviating rattling of the sash in the 1 or lowered position. Furthermore, it is understood that the ball 12 will be permitted a certain amount of rotative movement as to reduce friction and thus permit easy sliding movement of the sash within the frame.

Even though Ihave herein shown and described the preferred embodiment of my invention, it to be understood that the same is susceptible to changes fully comprehended by the spirit of the invention as herein de- 16;

scribed, and the scope of the appended claim. Having thus described my invention, What I claim as new is:

In an anti-rattling device for sliding Window sashes, an apertured flange adapted to be secured to a rail of the Window sash, an arm extending laterally from said flange and rolled upon itself to provide a cylindrical housing a disk like projection extending at 10 right angles to said arm for closing one end of said housing, said arm at the open end of said housing being provided With a plurality of fingers arranged in an annular series and bent inwardly toward one another, a ball partially projecting from said housing engaging said fingers and adapted to bear against a Window stop, and means for yield ably projecting the ball.

In testimony whereof I aflix my signature.

ALFRED THOMPSON GRANGER.
